报告摘要：Layered two-dimensional materials exhibit pronounced physical transport properties from their bulk counterparts due to reduced dimensionality and symmetry, and provides unique opportunities for applications such as nanoelectronics, energy storge and communication. Graphene is the first 2D material experimentally realized with thickness down to one atomic layer, and has been attempted to be a good candidate so as to replace silicon in integrated circuit for extending Moore’s law in the next generation.However, the absence of a band gap in graphene makes many device-related applications very challenging. In this talk, I will firstly review progress of graphene and my past work about the physical properties of graphene-based nanostructures. Secondly,I would talk about my main work about Chemical-doping-driven crossover from graphene to “ordinary metal” in epitaxial graphene grown on SiC. Finally, I would talk about my recent work in accordance with the progress of physical properties of 2D material heterostructures.
